Abstract
Described herein are acyl germanium photoinitiator for cost-effective and time-efficient method for producing UV-absorbing contact lenses capable of blocking ultra-violet ('UV') radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a method for making UV-absorbing contact lenses made by using an acyl germanium photoinitiator of the invention.
